Abstract

L'invention concerne un dispositif de ceinture de sécurité pouvant réduire la fréquence d'apparition d'un verrouillage d'extrémité lorsqu'on débloque la mise en place de la sangle et pouvant mettre facilement fin au verrouillage d'extrémité même lorsque celui-ci se produit. Ledit dispositif comprend un rétracteur de ceinture de sécurité pourvu d'un mécanisme de verrouillage qui bloque la rotation d'une bobine (2) dotée d'un rouleau de sangle dans le sens de tirage de la sangle par mise en contact d'un élément de roue à rochet (15) avec une roue à rochet (13), lorsque l'accélération du véhicule ou une accélération du tirage de la sangle excède une limite spécifique. La roue à rochet (13) est constituée de telle manière que plusieurs types d'encliquetages à rochet (T1) avec différents diamètres circulaires de déport sont disposés à une régularité adéquate dans le sens de la circonférence, ce qui permet ainsi de diminuer la possibilité d'apparition d'un verrouillage d'extrémité de sangle.
